Yesterday I set up a serial console to catch a frequent spontaneous reboot
that has been plaguing my machine since the upgrade to 2.2.1-R and
RELENG-2.2 970510. Attached below is the output from the panic and the
boot that followed.
What are my options to resolve this? Does the new 2.2.2 address any
kernel or SCSI bugs above and beyond RELENG-2.2? This only seems to
happen after periods of very high activity, such as running the Bovine rc5
client for serveral hours at a time. I am running the P6 at 233 MHz, but
I have extensive cooling measures in place, and it ran fine under the same
load and 2.1.5 for several months at a time, so I don't think that is it.
The only hardware addition made since the machine was a 2.1.5 machine that
never crashed was the Micropolis 3243W. Has anyone had particular
problems with this model and the 2940UW?
Thanks in advance for any help.
